Interview Process

The interview process started with an initial screening call that lasted about 30 minutes. In this call, the interviewer asked about my previous experience and projects I worked on. After passing the screening, I was scheduled for an onsite interview.

The onsite consisted of three rounds: one technical coding interview, one system design interview, and one behavioral interview. The coding interview focused on problem-solving using data structures and algorithms, and I faced a few LeetCode-style questions. During the system design interview, I had to design a scalable system for a particular feature used in the Snapchat app. Finally, the behavioral interview evaluated my cultural fit and collaboration skills within a team.

Overall, I felt the interviews were structured well and the interviewers were friendly. I was given useful feedback after each round, which helped me understand areas for improvement. I am currently waiting for the final outcome from the interviewers.

Technical Questions

  1. Two Sum (Array, Hash Table)
  2. Longest Substring Without Repeating Characters (Hash Table, Sliding Window)

Tips & Insights

  • Prepare for LeetCode-style coding questions focused on data structures and algorithms.
  • Be ready to discuss system design concepts, particularly scalable solutions.
  • Emphasize collaboration and cultural fit during the behavioral interview.
